    This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have been conducted on various AAS-CPB samples with different binder contents, silicate modulus (Ms: SiO2/Na2O molar ratio), fineness of slag and curing temperatures.

  • Mine backfill an overview

    equipment (mixer, pumps, pipelines) are necessary. A potential other drawback might be, that hydraulic backfill brings additional water into the mine and construction of dams may be necessary to isolate the backfilled excavations and to avoid outflow. The properties of backfill are determined by the following parameters (Moser, 2016):

    Rheological measurements such as viscosity, elasticity, processability, temperature-related mechanical change, and the yield stress value of mining tailings can be extracted easily from a simple measurement using a rheometer. Those values can then be easily correlated with the pumpability of a specific tailing formulation with given solids mass
